what you mean pot size doesnt determine plant size.......im here to disagree with that comment...and the pot size definatly does matter,you can feed that small pot of roots all you want and the plant will get root bound and do shit for you ok ,,i do know and have experienced it...if you dont want your plant super tall then put them in at least 5 gallon buckets and you can tie them down to the bucket to your desired size..its not hard...and still easily moveable. i have mine in 5gallon buckets now and i could easily move annytime.
